DIY jigsaw table - Patchwork quilt. Materials and tools sawing made a new jigsaw wood How to make a homemade jigsaw

A tabletop jigsaw machine will be useful to every craftsman who cuts out thin parts. However, it is not always possible and meaningful to purchase a full-fledged machine. In that case, get down to business and make it yourself!

The structure of a jigsaw machine - what lies inside?

Jigsaw machines are more related to special tools than to devices that are needed as to an experienced master, and for the amateur who manages the garage. Their purpose comes down to a special task, namely cutting out complex curved contours from sheet materials. A special feature of such machines is the execution of cuts without violating the integrity of the external contour. Most often, sawing occurs on wooden and derivative materials (plywood, chipboard, fiberboard), although modern machines equipped with appropriate saws can also work with other materials, for example, plastic or plasterboard.

Such equipment has found application in the music industry (manufacturing musical instruments) and, of course, in the furniture room. Those who like to make things in their own workshop also buy such units. The structure of a traditional jigsaw machine, designed according to all the rules, looks like this: the working surface on which the saw is mounted hides a drive (electric motor) and a crank structure underneath. The tension mechanism can be located either below or above the machine.

To process a part, it must be placed on the workbench. Many models have the ability to rotate it under different angles to make bevel cuts. The stops and guides on the surface, as well as the rotating mechanism, can be marked, which greatly simplifies and speeds up the work. The length of the cut depends on the length of the work table - most models are limited to 30-40 cm. Electric motor power is an important, but still far from the most fundamental factor, since the machine has a huge reserve of unclaimed power. For example, for a home workshop or even small production, an “engine” of only 150 W is sufficient.

The crank mechanism is much more important detail, because in this case the quality of transmission depends on it torque drive into a reciprocating motion directed in a vertical plane by means of a saw.

Standard jigsaw machines are considered to be devices with an amplitude of movement of around 3-5 cm and a vibration frequency of up to 1000 per minute. Many models provide a change of speed mode for different materials. The jigsaw file itself is usually made up to 35 cm long and is capable of sawing material up to 10 cm thick. The width of the files can vary in a fairly wide range - from very thin two-millimeter to coarser ten-millimeter, with a thickness from 0.6 mm to 1.25 mm.

Even the thickest and widest file will easily break if you do not provide sufficient tension along the entire length of the file. Leaf and coil springs are used for this. Quite often, such machines are equipped with an air pump, which cleans the cut from sawdust by blowing it, as well as a drilling unit. The latter device is especially useful, because in this case the master does not need to be distracted by the connection electric drill and drilling a hole - everything happens on the working plane of the machine. Of course, you have to pay for convenience!

How to make a jigsaw with your own hands from a manual jigsaw?

On the Internet you will find many different designs homemade machines, but most of them come down to repurposing into this device. By using your ingenuity and watching the video, you can easily make a homemade jigsaw from this tool. The jigsaw only needs a little modification. In fact, it plays the role of a machine drive and a crank mechanism, but the rest needs to be thought out and implemented.

Of course, manufacturers are trying to please consumers in this area as well, offering their own platform options for quick and convenient remodeling, however, in reality only you can make a device that suits your needs. So, the first step is to make a support table, for which they most often use sheet metal. You need to make a beveled oblong hole in it for the saw blade and holes for fasteners (countersunk screws are recommended), and attach the jigsaw to the bottom of the support table.

This structure can only be strengthened wooden table. You can go beyond this and install guide rails. The convenience of such a device lies in the fact that in addition to performing functions that are not entirely inherent to it, you can always disconnect the drive and with a slight movement of your hand turn it back into a manual jigsaw! If you constantly need this tool for work, it makes sense specifically for the machine - it will be cheaper than spending money on a real machine.

Advantages and disadvantages - we continue to modify!

But such a unit inherits not only the advantages of the tool, but also its disadvantages, in particular, the file is too wide for filigree work, which significantly limits the curvature of the lines. If there is a need for this, there will be a way out. So far, our machine differs from a classic jigsaw unit in the absence of springs that would ensure sufficient tension on the file. But it’s quite easy to build a simple rocker, which on one side will be under the tension of springs, and on the other, fixed to a nail file.

There is another option - to clamp the nail file between two guide rollers, but the first option is still more reliable. Don't forget to turn off the pendulum action on your jigsaw before you start using your homemade machine. There is another design - if your tool is powerful enough, then it can only serve as a drive in a structure of two rocker arms, between which a nail file is stretched. The movement is transmitted through a file attached to the lower rocker.

Machine from a sewing machine - giving a second life to old tools!

If you inherited a foot-operated or manual sewing machine from your grandmother or mother, consider yourself the owner of an excellent jigsaw machine! Of course, for this you need to “work a little magic” on the machine. First, remove the thread weaving device, which is usually located at the bottom of the machine. There is nothing complicated about it, just unscrew two bolts. Then we knock out the cotter pin and remove the drive shaft leading to the thread weaving mechanism.

Having unscrewed the top panel that protects the mechanisms, it is necessary to expand the slot in which the needle went. Be guided by the needs and width of the nail file that you will use in your work. Files for a jigsaw machine of this kind also need to be slightly modified, namely, cut to the maximum length of the needle that could be used on this machine. Grinding off the upper teeth and sharpening bottom part on the tip, all you have to do is insert the file into the needle holder and test your machine in action!

Since childhood, we have been familiar with the technology of sawing with a jigsaw. The principle is simple - a stationary part is placed on a stand with a technological cutout, the cut is made by moving the saw. The quality of work depends on the steadfastness of the hands and the skill of the worker.

In this way, you can literally cut lace from thin wooden or plastic blanks. However, the process is labor-intensive and slow. Therefore, many craftsmen thought about small-scale mechanization.

A simple design from the last century

Also in the magazine Young technician“Drawings were offered on how to make a jigsaw machine with your own hands. Moreover, the design does not involve an electric drive; the drive is powered by muscular force, like a knife sharpener.

The machine consists of main parts:

• bed (A)
• work table (B) with slot for canvas
• lever system (B) for holding the saw blade
• flywheel (G), which is the primary drive pulley
• crank mechanism (D), combined with a secondary drive pulley, and driving the levers (B)
• pedal assembly (E) with a crank mechanism driving the flywheel (D)
• saw blade tensioner (W)

The master uses his foot to move the flywheel (D). Using a belt drive, the crank mechanism (D) connected to the lower arm (B) rotates. A file is stretched between the levers; the degree of tension is regulated by a lanyard (G).

With a well-balanced flywheel, sufficient smooth running of the saw blade is ensured, and such a homemade jigsaw machine allows you to massively cut out the same type of workpiece, saving time and effort. In those days, jigsaw files were produced in the form of a flat, unidirectional strip.

Therefore, to obtain patterns of complex shapes, it was necessary to rotate the workpiece around the canvas. The dimensions of the workpiece are limited by the length of the arms (B).

From a mechanical jigsaw to an electric one one step

The foot drive cannot provide real freedom of action and uniformity of the saw stroke. It makes more sense to adapt an electric motor for the crank mechanism. However, if you use a tabletop jigsaw occasionally, there is no point in making stationary structure with its own motor.

Manual power tool very popular both among amateurs and among professionals due to its obvious advantages, namely:

• comparative cheapness and availability;
• compactness;
• mobility.

Reverse side of these unconditional advantages is the presence of such shortcomings, How:

• relatively small continuous operation time;
• small achievable accuracy;
• insufficient quality of processing.

Obviously, these shortcomings are free professional stationary solutions - machines and machines on massive frames. As a result, they are quite not cheap, but the main thing is that they need to be placed somewhere. What to do if it is not possible to equip workshop, but I want to improve quality works? This question is asked by many of those who are passionate about a serious hobby, and even just beginners. masters

In our article we will talk about decision, allowing to eliminate known shortcomings manual jigsaw.

Advantages of a tabletop jigsaw

The general ones discussed above flaws hand power tools are fully inherent and jigsaw.

Its main advantage is mobility – implies exclusively manual movements And fixation tool. That is, in reality it turns out that:

1. Very difficult to do smooth, a clear cut: the slightest extra movement - and a visible flaw appears in the cutting line. Those included in the kit guides do not save due to their insufficient rigidity;
2. Corner tilt The saw blade in relation to the workpiece is actually not controlled in any way. And even in the simplest case straight cut when the canvas perpendicular jigsaw sole, the result may disappoint. There are at least two reasons:
   • Saw blade – elastic and can bend during the cutting process, the free edge of the file is not limited by anything;
   • On affordable (read: cheap) models, it’s quite often ideal direct the angle between the file and the sole is difficult reach due to the very design of the cheap stamped grounds.

Interesting Mark, what, say, American craftsmen use manual jigsaw is quite rare. For example, when you need cut opening in the kitchen countertop for installation sinks In other cases, they prefer to use stationary band saws of various sizes. Such saws are completely devoid of some disadvantages (mentioned above), and are fully endowed with others: dimensions, weight and... price.

To summarize above, we can confidently conclude that, in some way securing jigsaw on the workbench, it is possible to a certain extent win some of its shortcomings. And if you provide guides rollers for free edge canvases files, you can get a completely even cut. And clean - at correct selection the file itself.

Therefore, special jigsaw table will significantly improve the quality of work with this tool.

Of course, you shouldn’t think that in this way you can get “cheaply” full-fledged tape saw. But more on that a little later, now – briefly about what will be needed for production.

Materials and tools

Materials can be used from those available at hand. I would just like to note that the working surface(“countertop”) must be level and sufficiently tough, Therefore, when choosing a material, you need to keep the following points in mind:

• Can be used plywood, however, thin (less than 12 mm) plywood is susceptible to warping, and it’s not a fact that the existing piece will be quite even.
  Waterproof would be preferable laminated(“formwork”) plywood thickness from 12 mm.
• If we talk about (chipboards), then in general, the thicker they are, the better - the more rigid. Ideally - a piece quality laminated kitchen table tops or "post-forming".
  Disadvantages: less reliability fastenings tool, you need to take a more responsible approach to choosing fasteners.
  From advantages, perhaps the main thing is accessibility and simplicity: you can order all set parts according to their dimensions in any furniture workshop. Thickness It’s better to take not the standard 16 mm, but a larger one (for example, 22 mm).
• Metal its properties are almost perfect, but it is quite difficult to find in everyday life suitable sizes piece, polished and smooth. Besides, do in it required holes somewhat more labor intensive, then it is wise to use drilling machine.

Set of necessary tool will depend on the selected materials, but in general it is approximate scroll something like this:

• pencil, roulette or a ruler, a carpenter's square - for marking;
• square will also be useful at the stage final assembly and settings;
• screwdrivers and nuts keys according to the selected fastener;
• screwdriver or drill, drills for fasteners, self-tapping screws (screws).

In addition, you will need rectangular metal bracket, two identical bearing and fasteners. Actually myself jigsaw will also come in handy.

Manufacturing stages

Regardless of the chosen material necessary:

• manufacture base and connect to the working surface with holes for attaching the sole of the tool;
• make a system brackets for the upper saw blade guide;
• collect and adjust table.

Base and work surface

Dimensions grounds are selected based on dimensions available jigsaw and are indicated approximately.
The dimensions of the working surface are also indicated approximately, from the bracket mounting side it mounted flush with the base, on the other three sides made small projection for ease of fastening rigging(clamps, stops, etc.).

Device bracket with guide bearings is clear from the figure.
Sizes can be chosen individually, but some Necessarily need to be kept in mind.

which limit the movement of the file to the side, you need pick up based on the size of the files you plan to use. Width the bearing itself (in reference books it is indicated by the letter IN) must not be larger than the width files, so as not to dull its teeth.

So, for example, if width metal file blades (T123X, T118A) usually more than 5 mm, then they will be suitable bearings with size B 4–5 mm, for example:

Wherein prefer follows the model with the letters ZZ, 2RS as the most protected from exposure to dust, which will certainly occur during the cutting process.

Saw blades tree, on the contrary, they can be narrow (T244D about 3.5 mm) and very narrow (T119BO about 3 mm, which can be used in our case). As an option - bearing 100093 (aka 693, 3 x 8 x 3 mm).

Selected bearing fastener: M3 or M4 screws, nuts (preferably “self-locking” with nylon insert that prevents spontaneous unscrewing).

Distance between axes bearings are also calculated based on the size of the files, thickness canvases may be within from 0.9 to 1.7 mm.

For example, thickness blade T244D is 1.25 mm, and T123X, T118A – 1 mm. It is better to round in big side.

Assembly and adjustment

Bracket can be secure in the following way

This method of fastening will make it possible adjust and the height of the guide bearings in accordance with the length of the saw, and (using a square) perpendicularity the saw itself relative to the work table.

As mentioned above, you shouldn’t delude yourself - even though it’s no longer easy jigsaw, but still not a band saw. Here are some tips:

• • IN band saw movement saw blade occurs only in one direction – top down, due to which the workpiece is pressed against the table by cutting forces.
    It is not possible for the workpiece to explode upward, since the pendulum of the jigsaw moves and returnable movement.
    Therefore, the workpiece needs to be well press to the working surface of the table and the most important thing is to feed (move) the workpiece as much as possible slower.

Note! More revs and less feed are much better than the other way around.

• When working with a jigsaw (with or without a table) it is useful to remember that move jigsaw files are usually about 15–20 mm, You need to read this value for your instrument in the instructions or determine it yourself. Material thicker than this size should only be sawed with divorce teeth Otherwise shavings will not be completely removed, which can lead to overheating and jamming of the canvas.
• Between the working surface of the table and sole jigsaw can lay a sheet of dense rubber, having previously made a cut for the file. Assemble the table and let the canvas work a little idle, so that the canvas “grinds” to the slot in the rubber. This will protect moving units of an inverted jigsaw from a large number sawdust, for which it is not designed, because in normal mode the tool designers clearly did not count on such a number of them.
• Protective glasses - necessary. You also need to organize the device to be turned on via pedal or provide another way instant turning off the tool. But this is a topic for another article.
• Do not be afraid creatively think and improve your tools, because any idea - just a starting point for creativity, and universal there are no solutions.

What to do when you need a jigsaw but don’t need to buy one? You can make a jigsaw with your own hands. There are many ways to make or repair such a tool. Let's look at the simplest and most accessible of them.

Manual jigsaw - simple, fast and affordable

How to make a jigsaw quickly from available and inexpensive materials? Here's the easiest way.

List of tools and materials:

• plywood sheet (10 mm);
• plywood sheet (4 mm);
• steel sheet (2 mm);
• bolts and nuts;
• drill;
• chisel;
• sanding paper;
• file.

The basis hand jigsaw serves as a staple, it should be prepared from plywood sheet(10 mm). Next, it is recommended to make thickenings for the tool handle from more thin plywood(4 mm). These thickenings must be glued to the handle on both sides, which will ensure more convenient operation in the future. Sand the bracket and handle well using sanding paper and a file. It is necessary to cut out the steel plate with a chisel, and then clean the clamping jaws with a file. After this, drill slots in the jaws with a drill, and then use a sharp chisel to cut notches inside the clamping jaws. In the left clamping jaw, modify the slot for the bolt; for this you need to make a thread. Attach the jaws to the bracket, then screw the bolts into the left clamp, securing them with nuts.

Table jigsaw: two manufacturing options

The desktop fixture can be made either new or by modifying or repairing improvised means.

Making a new benchtop mechanical jigsaw will require the following tools and materials:

• duralumin pipe;
• plastic base;
• clamps;
• screws;
• copper sheet;
• drill.

First you need to prepare the frame; for this purpose it is better to use an aluminum pipe. When making the frame, it is necessary to provide a passage through which the cord will be laid to provide power. A copper sheet should be taken to make a U-shaped frame, which will subsequently need to be attached to the frame itself. At the junction of the frame with the jigsaw handle, screw the frame with screws. In the plastic base, use a drill to drill a hole for the file, as well as slots for fasteners. Attach the jigsaw to the prepared plastic so that the file passes through the hole. Using clamps, attach the finished tool to a flat surface, such as a table.

A hand-held device based on sewing machine, This perfect option, if repair sewing machine is not as important as making such a tool. List of tools and materials:

• sewing machine (you can use either a foot- or hand-operated model);
• file;
• needle file;
• drill.

After unscrewing the bolts at the bottom of the sewing machine, you should remove the entire threading system. Next, knock out the metal fastening rod and remove the drive shaft of the thread weaving system. The panel covering the sewing machine parts can be easily removed by unscrewing 2 more bolts. Carefully remove the needle. The needle slot needs a little repair - it needs to be widened to accommodate a file. To do this, it is better to cut the hole using a needle file, focusing on the dimensions of the file itself. After this, adjust its size to the maximum possible needle size by cutting off the top of the file. After grinding down the upper teeth with a file and the lower part on the tip, you can proceed to the next step. The prepared file must be placed in the place of the former needle - in the needle holder. After this, you should turn the wheel and check:

• so that the saw does not come into contact with the panel and the presser foot;
• so that in the upper position the plywood passes freely under the saw;
• so that the material can be drawn smoothly.

Such a jigsaw will do in order to work with materials from plywood, balsa wood and plastic, and if you use an electric machine, you will get an electric jigsaw.

Jigsaw machine is a device that provides high-precision implementation of operations related to the processing of workpieces made of different materials. Using such a machine you can make even or curved cut of varying complexity on sheet blanks. When cutting on the inner surface, the outer edge of the material does not change. This machine can be used to work with timber, plastics, and some types of metals. If you have to use a jigsaw frequently, this machine is the perfect choice. would be better suited for this purpose.

Design and operation

The main components of the entire structure of the machine are the table, motor, saw, crank and tensioning mechanisms. In addition, there are additional functional elements.

The material being processed must be on the work table. The material from which the countertop is made is very important. Choose a cast rather than stamped table. On the working surface there may be additional rotating mechanisms, with the help of which you can change the angle of inclination of the table and cut. The dimensions of the table are determined maximum dimensions processed workpiece. Most models have a saw length of 300 to 400 mm.

The power of the power unit affects the list of materials that can be processed on a jigsaw. If you plan to process not only wood, then you need to choose models with a power greater than 200 W. For the home handyman A 150 W device will be sufficient.

The jigsaw is the main working unit of the equipment. The file is selected depending on the type of cut and the density of the workpiece; in addition, you need to take into account the width and thickness. Small devices can cut timber up to 50 mm thick, more powerful professional machines They can also handle workpieces up to 100 mm in thickness.

The torque created by the motor is converted by the crank mechanism into the movement of the sawing unit. Stretching device tensions the saw as it moves across the material.

The operating principle of this device is quite simple. The workpiece is mounted on the table, then, under the control of the master, the saw makes the cut.

A jigsaw for wood has a number of advantages over other more simple devices. First of all, the device guarantees a high-quality cut. The machine makes it possible to carry out longitudinal, transverse or angular cuts with maximum accuracy, with the formation of a smooth edge. Another advantage is the fact that the master’s hands remain free, therefore, the workpiece is easier to control, therefore, with a certain level of skill, the most complex bends can be obtained. It is also worth noting that the presence of protective covers minimizes the possibility of getting herbs.

Files for a jigsaw most often have a length of up to 35 cm and can cut material up to 10 cm in thickness. The width of the files can be very different - from the thinnest two-millimeter to the coarse ten-millimeter, with a thickness from 0.6 mm to 1.25 mm. Please note that even the thickest and widest files will easily break if the necessary tension of the file along its entire length is not ensured. Leaf and coil springs are responsible for tension.

Quite often, such a machine has an air pump that cleans the cutting line from sawdust, as well as a drilling unit. The block is extremely useful, because with it, the master is not distracted by connecting an electric drill and drilling holes - everything is done on the working plane of the machine. But such machines also cost more.

There are several options for creating a jigsaw machine with your own hands. For the most simple machine A jigsaw table can be created quite quickly. The main advantage is simplicity. The device is simply mounted on a tabletop or workbench and can be easily disassembled when work is completed. The downside is the small area. The simplest machine has the following components:

• plywood sheet
• mounting screws
• several clamps.

As a working base, you can take a sheet of laminated plywood, in which you need to drill holes for mounting fasteners and for the file itself. Plywood should be taken with a thickness of over 10 mm. In this case, it is also necessary to drill holes for the mounting screws in the sole of the jigsaw. Homemade design attached to the workbench using clamps. It is worth noting that the screw heads for fastening must be recessed into the surface of the sheet so that they do not interfere with operation. Such a device can easily cope with the processing of small workpieces, the thickness of which does not exceed 30 mm. A drawing of such a machine can be found on the Internet and assembled with your own hands in your workshop or garage.

The second version of the machine has the following components:

• chipboard bed
• vacuum cleaner tube
• piece of laminated plywood for the machine cover
• confirmants.

This option is a little more difficult to assemble, however, this task is completely solvable. The bed is made from chipboard. It has a back wall and two sides. In order to get to the power button it was not difficult; there was no need to install the front wall. IN back wall you need to drill holes for the vacuum cleaner tube and cord. It is better to cut the cover for the device from a piece of laminated plywood 10 mm thick. After this, the entire structure is fastened with confirmants. The jigsaw itself can be installed in a similar way to the previous option. On a machine created in this way, you will be able to process larger workpieces. Of the minuses, we note that when working with large workpieces, the jigsaw saw can deviate in both directions and even backwards. Consequently, the quality of the cut decreases. However, this can be dealt with. You just need to install it on homemade machine bracket, which is a stop. In this case, the jigsaw blade will move between two 11 mm bearings screwed to an L-shaped steel strip. The back of the canvas will rest against the wall of the bracket itself. Such a system will prevent the web from deviating from the specified trajectory.

The bracket must be attached to a frame, which is created from 50 by 50 mm bars. The frame is lowered or raised, it all depends on the length and thickness of the workpiece being processed. To ensure the mobility of the frame, it together with the stop must not be firmly fixed to the side of the machine, but pressed against it with a hardboard, steel or textolite plate. Next you need to install vertical stand frame between the hardboard and the frame. The machine will become even more convenient if you attach an additional limit bar to it, with which you will cut the material into blanks of equal thickness and length. This limiter is attached to the machine using clamps. It can be made from wooden beam, as well as aluminum or steel corner.

To create a table for a jigsaw from chipboard, you need to have certain carpentry skills, because the process of connecting its frame with legs must be done in a tongue-and-groove manner. The tongue and groove itself can be replaced with a connection using dowels, wood glue and self-tapping screws. The cover must be removable to ensure access to the tool during repairs. To create a multifunctional machine, it is worth providing a place for attaching a manual milling machine. For the table you will need the following materials:

• block 80 by 80 mm
• block 40 by 80 mm
• a piece of laminated plywood or laminated chipboard sizes 900 by 900 mm.

First you need to measure the gap between the legs. Optimal distance 60-70 cm. The bars for the legs and drawers are obtained in the course of longitudinal sawing beams 80 by 80 mm. The height of the legs is selected at the discretion of the master. Each end of the legs and drawers must have two holes for dowels. Similar holes should be present on the sides of the legs. Next, you need to coat the dowels halfway with glue and insert them into the ends. After this, you can begin assembling the entire frame. In this case, the frame will not be disassembled.

All surfaces at contact points must be coated with glue. However, self-tapping screws won't hurt either. They will make the structure more durable. Holes for self-tapping screws must be prepared in advance. The lid is attached to one of the drawers using hinges. A slot needs to be made in the cover to facilitate removal and installation of the jigsaw.

In the back of the tabletop you need to screw two strips in which a quarter is selected. It includes the sole of the jigsaw. The strips must have holes for further installation of bolts or clamping screws. As a result, you will get a fairly simple and spacious table. Thick chipboard or plywood will help to achieve high strength of the lid. Sheets must be thicker than 20 mm.

A standard jigsaw blade is not suitable for creating complex patterns in plywood. For these purposes, a thin file is needed. It can be attached to hand power tools using an unusual device. The jigsaw, as in previous versions, is attached to the tabletop. But the thin nail file must be taut, easy installation will not work on a pendulum. To facilitate the procedure of tensioning the canvas, it is worth creating a rocker arm from a block. In this case, the tension of the file will be provided by a spring. The lower loop of the spring must be put on the transverse pin, and the upper loop is inserted into the adjusting screw, which changes the tension force of the damper.

Note that everything wooden blanks for such machines must be made of hard wood. Since a jigsaw machine does not have the ability to fasten a blade with a thin section, you can remake a piece of an old blade by pre-drilling a hole in it and equipping it with a screw and nut, as well as a clamping plate. The rocker arm must contain a vertical slot into which a second steel plate is inserted. It is attached to the rocker with screws.
